Value Over Replacement Player. The number of runs contributed beyond what a replacement-level player at the same position would contribute if given the same percentage of team plate appearances. VORP scores do not consider the quality of a player's defense.

Here is an example of the Value Over Replacement Player spectrum based on the 2011 season:

VORP for position players consists of batting runs above average (BRAA), position adjustment (POS_ADJ), baserunning runs above average (BRR - which includes - but is not limited to - stolen bases and times caught stealing ), and an adjustment for replacement level (REP_ADJ).
